1. The crystal structure formed by the circuit plate is different from the gold plating of the circuit board. Shen Jin is much thicker than the gold -plated thickness. Shen Jin will be golden yellow more yellow than gold plating, and customers are more satisfied.

2. Shen Jin is easier to weld than gold plating, which will not cause poor welding and cause customer complaints. Shen Jinban's stress is easier to control. For products with Bangding, it is more conducive to the processing of Bangdin. At the same time, it is because Shen Jin is softer -plated, so Shen Jinban does golden fingers is not abrasion.

3. Sinking gold board only has nickel gold on the pad, and the transmission of signals in the skin -tech effect will not affect the signal in the copper layer.

4. Sinking gold is more dense than plating, and it is not easy to produce oxidation. Make craftsmanship according to your own demand for the product.

5. As the wiring becomes more and more dense, the wire width and spacing have reached 3-4mil. Gold plating is easy to generate short circuit. The Shen Jin board only has nickel gold on the pad, so it will not produce a short circuit.

6. The golden plate of the circuit board only has nickel gold on the pad, so the combination of welding resistance on the line and the copper layer is more firm. The project will not affect the spacing when compensation.

7. It is generally used for relatively high -demanding boards. The flatness is better. Generally, the circuit plate Shen Jin is used. Sinking Jin generally does not have the black pads after assembly. The flatness of Shen Jin board is as good as the life -long life.
